Periplaneta Americana. American cockroach's are also known as waterbugs, flying water bug and, in some areas of the South, the palmetto bug. It is the largest of the common species, growing to 1.5 inches or more in length. It is reddish-brown, with a pale brown or yellow border on the upper surface of the pronotum.
Thanks for the question. The radial artery in the wrist can be used to measure the blood pressure. But in my opinion, the brachial artery blood pressure measurement is better than radial artery for the following reasons: 1.The blood pressure at the wrist is higher for systole, lower for diastole, and about the same for mean or average pressure. The amount of difference depends on the stiffness of the arteries.ut in my opinion, the brachial artery blood pressure measurement is better than radial artery for the following reasons: 1.

Low Blood Pressure and the Arterial Wall The space within the intravascular space is variable, based upon the muscle tension in the walls of the arteries. Adrenalin (epinephrine) increases tension and causes the arteries to narrow and support blood pressure.
